IMPROVEMENT IN LUBRICATORS.

Specification forming part of Letters Patent No. 214,311, dated April 15, 1879; application filed February 1, 1879.

To all whom it may concern.'

Be it known that l, CHARLES H. PARsHALL, of Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Lubricators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in lubricators and attachments for locomotives, the object being to provide a lubricating apparatus ot' such construction and arrangement of parts that the lubricator may be at all times under the immediate control of the engineer or fireman, and the amount of lubricating material supplied to the cylinders readily ascertained and regulated, that both cylinders of a locomotive-engine be supplied from a single lubricating apparatus, and that the connections may be adapted to expand and contract without injury to the apparatus; and to these ends my invention consists, first, in the combination, with the dry-pipe of a locomotiveboiler, of a lubricator provided with a visible hydrostatic drop-feed and with independent steam and oil pipes furnished with a slip-joint and connecting the lubricator with the drypipe, whereby the amount of oil fed to both cylinders is readily ascertained by the engineer and regulated as desired.

My invention further consists in the combination, with the dry-pipe of a locomotive-boiler, of a lubricating apparatus connected therewith and with the steam dome in such a manner that the connecting-pipes may expand and contract Withoutcausing any undue strain either on the lubricating apparatus, dry-pipe, or shell of the boiler.

My invention further consists in the several details in construction and combinations of parts, as will be hereinafter explained, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a vertical section of a lubricating apparatus located within the cab of a locomotive and connected with the dry-pipe in the steam-dome 0f the boiler. Fig. 2 is a view, in perspective,

of my improved lubricator. Fig. 3 is a transverse section of the oil-receptacle. Fig. 4 is a modification.

A is the engine-cab; B,the boiler, and D the steam-dome.

Within the dome D is located the ordinary dry-pipe E, in the upper portion of which is located the throttle-valve F, all of which parts are of the ordinary or of any desired construction.

Gr is a lubricator, supported by an upright frame, a, attached tothe boiler or to any convenient portion of the cab.

It is preferable to secure upright a to the boiler, so that there will be no uneven motion between the body of the lubricator and the conduits by which the connections with the dome are made.

Lubricator G is divided into two parts-viz., the oil-receptacle b and condenser c-which parts are constructed of metal and connected in any desired manner.

Oil-receptacle bis cast in a single piece, with a recess, d, in one side thereof, Within which recess is placed the glass indicating-tube H, the latter being of less length than the oil-receptacle, to form openings e f leading from the upper and lower ends of the glass tube to the interior of the oil-receptacle.

I represents a perforated pipe, the upper end ot which is screwed into the lower partition ofthe condenser, while its lower end projects through the bottoni of the oil-receptacle and receives a nut, g, which latter, being turned as a ball which ts snugly into a socket in the bottom of the oil-receptacle, serves to bind evenly the latter to the condenser, the upper edge of the oil-receptacle being received within the downwardly-projecting ange h formed on the bottom of the condensing-chamber.

Waste-cock g is combined with nut g for the purpose of drawing oft the wat-er from the glass tube and oilreceptacle when desired.

J is a screw-threaded plug tted into the top ofthe condensingchambcr. The plug J being removed, oil is inserted through the opening and iIlows into the perforated tube I, and from thence into the o1l receptacle. Condensing chamber c is provlded with a screw-threaded limb or stem, K, which 1s divided into a steam-passage, L, and oil-feeding passage M by means of the portion N. ln the bottom of thc condenser is located a downwardly-closing check-valve, j, by means of which a communication may be established between the oil-receptacle b and the oil-passage M.

Connecting with the steam-passage Lisa vertical steam pipe or conduit, It, which extends nearly to the top ot` the chambered nut I. Nutl being chambered allows the steam to be supplied to the condenser at the desired height above the bottom thereof, to insure a column or body of condense-water in the condenser ot'the requisite height; and, t'urther, the nut enables the steam-pipe to be blown out and cleansed when necessary. In the opposite side of the condenser is formed a chamber, Q, having an opening. in, through the same, which is governed by a screw-valve, n, the latter serving to regulate the amount ot' water to be admitted to the interior of chamber Q from the main chamber of the condenser. Rising from the bottom ot chamber Q is a vertical partition, o, wluch extends nearly to the top of said chamber, the partition preventing a direct com munieation between the condenser and oil-receptacle, and insuring a column of water within the chamber equal in height to that of partition o. To thc bottom ot chamber Q is attached a feed-water pipe, lt, which extends downwardly any desired distance into the oil-receptacle, and then by a return-bend is carried upwardly, and is inserted in the upper end of the glass tube Il.

A steam-pipe. S, is screwed upon the screwthreadedstemK of the condensiiig-chamber,

and extends through the frame-work of the cab, through the shell ot' the steam-dome, and is screwed into the side ot'the dry-pipe. l

To provide for the contraction and expansion ot' steam-pipe S, the shell ot' the dome is furnished with a sleeve, T, which is firmly sev cured to the dome, and serves as a passage for steam-pipe S. Sleeve 'l is provided with a follower or packing-cap, p, which insures a tight joint between the sleeve and steam-pipe. By means of this construction the steam may t have an endwise movement due toits expansion and contraction, without `atecting the shell of the steam-dome,and without opening any joint or seam between the shellot' the dome andthe steam-lupa Within thesteampipe S is placed an oil-feed pipe, N, one end of which projects into the dry-pipe. while its opposite end is screwed into the oil-passage M in the condenser.

The operation ot` my improved lubricating apparatus is as t'ollows: Steam enters the steam-pipe S from the dry-pipe, and tlows through the vertical steam-pipe in the condenser to the main chamber, where it is condensed. rlhe condense-water is t'ed to the chamber Q in any desired quantity, and t'rom thence tlows downwardly within the returnbend pipe to the upper end of the glass indieating-tube. The return-bend pipe serves a double function, viz: 1t conducts the warm condense-water through the lubricating material, thus keeping the latter at the proper temperature to retain it in a limpid condition m1- dcr all degrees ot' temperature. Again, the return-bend pipe forms a trap, which is always tilled with condense-water, and serves as an effectual water-seal to prevent any flow ot oil into the condenser. As the water issues from the end of the return-bend pipe it falls into the glass tube in drops. As the oil stands at the same height in the glass tube that it does in the main oil-receptacle of thelubricator, the drops of water fall the length of the glass tube and pass outl into the lower end of the oil-receptacle. The drops of condense-water entering the oil-receptacle operate to displace au equal quantity of oil, and cause the latter to raise the check-valve and How through the oil-feeding pipe into the dry-pipe, and there mingle with the steam passing to the valvechest and cylinders of the locomotive.

The engineer can thus readily ascertain the amount ot' oil being fed to the engines, by inspecting the glass tube of the lubricator and ascertaining the number of drops of water falling through the tube in any given time, and the amount of oil to be fed can be easily regulated by varying the admission of condense-water, by changing the opening ot' the feed-valve.

When the oil-receptacle has become filled with water, it may be emptied by opening the waste-cock, allowing the water to escape, and the oil-receptacle again filled.

.The construction ofthe oil-receptacle with the glass indicating-tube seated inside the periphery of the saine is an important feature of my improvement, in that the glass tube is thoroughly protected, and hence not easily broken or displaced; and, further, the apparatus isrcndered more compact and attic-tent by reason of such an arrangement of parts.

The oil is fed directly to the steam in the dry-pipe, andhencc is conducted t0 both valves and cylinders of the locomotive. This enables the engineer togovern the flow of lubricants to both engines by ia supply ot' lubricant contained in a single lubricating apparatos.

The connection between the lubricator and the dry-pipe being `formed by aslip-joint allocomotive or other boiler, of a lubricator constructed with a visible hydrostatic drop-feed, and provided with independent steam and oil conduits connecting the lubricator with the dry-pipe, said conduits furnished With a slipjoint, whereby the parts are not injured by their unequal expansion and contraction, substantially as set forth.

2. The combination, with the dry-pipe of a locomotive or other boiler, of a lubricator, and a steam-pipe connecting the lubricator and dry-pipe, said steam-pipe provided with a slipjoint at the point of its passage through the shell of the steam-dome, substantially as set forth.

3. The combination, With the dry-pipe of a locomotive or other boiler, of a lubricator, a steam-pipe connecting the lubricator and drypipe, and a sleeve and packing-follower forming a slip-joint between the shell of the boilerdome and said steam-pipe, substantially as set forth.

4. The combination, with the dry-pipe of a locomotive o'r other boiler, of a lubricator provided With a condensing-chamber, a steampipe connecting said condensing-chamber and dry-pipe, and an oil-pipe located Within the steam-pipe, and serving to convey oil from the lubricator to the steam in the dry-pipe, substantially as set forth.

5. The combination, Wit-h the dry-pipe of a locomotive or other boiler, of a lubricator provided With a condensing-chamber, a steam pipe connecting said condensing-chamber and dry-pipe, the steam-pipe being furnished with a slip-joint, and an oilpipe located Within the steam-pipe, and serving to convey oil from the lubricator to the dry-pipe, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 14th day of January, 1879.
